As shown in Figure 4, improved blade assembly 60 is installed on the pin shape pivot 100 that is fixed in rotary mode, and the latter then is installed on the framework 62 of printing machine.This blade assembly comprises blade unit 64, it be positioned at the nethermost ink roller 72 of ink roller group and contact.Blade assembly 60 rotates between two operating positions usually, and when it was in first operating position, blade unit 64 came with the ink roller disengaging, thereby does not come in contact between blade unit 64 and the ink roller; When it was in the second place, blade unit 64 contacted with ink roller 72, so that clean, foul was disposed from ink roller 72.
The rotation of blade assembly 60 between above-mentioned first and second operating positions realizes that by a driver 65 this driver 65 is fixed on the printing frame 62, and it matches with blade assembly 60, makes it around pivot 100 rotations.Preferably adopt air impeller, because generally adopt compressed air in the printing machine machine room.
As shown in drawings, this blade assembly 60 also is can manually operated mechanism, and it can either sacrificial meat be a kind of override when driver 65 breaks down, and also can himself blade assembly 60 be forwarded to the device of its operating position as relying on.A driving handle 150 has been installed on frame 62 in a spiral manner, and this handle comprises a fixed axis 152, and it matches with a support 154 that is installed on the blade assembly 60.The two ends of spring 156 are fixed on support 154 and the frame 62.In when operation, the operator of printing machine can rotary handle 150, makes fixed axis 152 press to support 154, allows blade assembly 60 rotate around its rotating shaft 70 clockwise directions, thereby and ink roller 72 contact.By above-mentioned driving, spring 156 is compressed, thereby a bias force will be provided, the operator with opposite direction rotary handle 150 and axle 152, when blade assembly 60 and ink roller 72 are disengaged, impel blade assembly 60 to rotate around pivot 100 counter-clockwise direction.
Blade assembly 60 comprises a microscler blade 66, it has a semi-stiff bendable member 68, preferably made by rubber, plastics or analog, it contacts with the ink roller 72 that is positioned at extreme lower position, is used to scrape off printing ink, solvent and foul on the ink roller.This flexible 68 preferably has enough flexibilities, avoiding damaging the surface of ink roller 72, but should have enough elasticity again simultaneously, printing ink, solvent and foul can be scraped off required hardness from ink roller 72 fully so that provide.Blade assembly 60 comprises a catch tray 80 that is positioned under the blade unit 64, and its length direction parallels with the axis of ink roller 72.As shown in drawings, this catch tray has generally speaking open end 81, is used to make the printing ink, solvent and the foul that scrape off from ink roller 72 to be collected within the catch tray 80 by receipts.Known to the common technical staff of technical school in this technical field, catch tray 80 also can adopt and be suitable for printing machine each makes things convenient for other shapes of user, to realize above-mentioned functions.
Catch tray 80 can be made with material that can mold pressing, for example steel, plastics; Rubber, vinyl or any suitable cheap material (for example stamped metal of aluminium, galvanized iron sheet and so on) yet, when trending towards adopting disposable catch tray, when not preparing to reuse, also can use the paper material manufacturing (be preferably in and be coated with the last layer watertight composition in such catch tray, for example cured or plastics) such as cardboard.
Catch tray 80 also can make the unit of non-once, constitutes a permanent member of blade assembly.As described below, catch tray 80 can serve as a contrast last layer absorbent material 91, is used to protect the inside of catch tray, makes it not contaminated, and collects printing ink and solvent that the quilt scraped by ink roller group 70 dissolves.Like this, in the process of cleaning, just can protect catch tray 80 easily, make it not contaminated.
In addition, catch tray 80 also can adopt as the mode known to the those of ordinary skill in this technical field, is designed to be able to the structure that removes from blade assembly 60.Adopt this mode, in case after carrying out cleaning operation, when catch tray 80 was filled the printing ink that is collected and solvent, the operator just can remove contaminated catch tray 80 from support 82, change a clean catch tray.Preferably contaminated catch tray 80 is put aside, clean subsequently, so that reuse.
It is the unit that can remove that catch tray 80 also can be made into, and it is suitable for just being thrown away after filling printing ink and solvent.Adopt this mode, can handle regulation, contaminated catch tray 80 former states are fixedly thrown away, so that convenient and treatment of printing ink and solvent apace according to printing ink that allows and solvent.As adopting permanent collection disk, rotatable L type support 82 as the part of blade assembly 60 supports that disposable catch tray 80 is consistent with the size of support 82 basically, also can improve support 82, make it to have a plurality of, support catch tray 80 with known removable mode for intermediate plate or miscellaneous part known to the those of ordinary skill in the technical field.In order to prevent pollution to each system unit, the invention provides a shielding harness 170, be used for protecting take up assembly 60 and catch tray 80, make their unlikely making dirty in cleaning process.
The material that is used to make shielding harness 170 must satisfy the basic demand of a disease.This material must be heat-resisting, so that can bear the temperature (typical temperature range is 10-150 ℃) that is run into usually in operating process.
This shielding material also must have lower friction system (μ), thereby blade 68 can smoothly and effectively be moved on cylinder 72.In use, according to the tectal difference of cylinder (for example steel, rubber or cloth), coefficient of friction can be different.The dynamic friction coefficient of shielding material should be within 0.01 to 0.40 scope, so that no matter under the situation that applies how many solvents in system, the level and smooth ground roll tube of blade is contacted.
It is many-sided adopting the advantage of low friction systems material; It can prevent to produce too much heat and wearing and tearing, and this point does not apply in cleaning process under the situation of enough solvents and seems especially important; It can prevent that blade accidental damage cylinders of printing press and vent in the sides of a garment from drawing under the cylinder, and this phenomenon may take place when friction between solvent and blade 68 and the ink roller 72 increases lacking.
Another characteristics are that shielding material must relatively approach (for example within 0.48 to 10mils scope), so that keep the geometry of blade 68a, make blade 68 can clean ink roller 72 effectively.
Other required basic mechanical properties of shielding material comprise: wear resistence, chemical stability (promptly can resist all kinds of solvents used in cleaning process), excellent in shape stability and excellent mechanical intensity under higher temperature.Some kinds of materials are tested, being comprised: PTFE film " KAPTON " film, VHMW polyethylene, they are all produced by 3M company; Various types of paraffin paper comprise " frozen-pack paper ", " DELI tin foil ", " SNOWFIBRE-KOLD LOK polymer ", and they are all produced by JAMESRIVER company; And polytetrafluoroethylene (PTFE).Find that through test its thickness can satisfy above-mentioned requirements well at the about polyester film of 0.5-2mils (being produced by DUPONT company), when its thickness can provide best effect during for 1.0mils.(do not apply solvent) when carrying out dry run, polyester film is 0.20 to the dynamic friction coefficient with the tectal cylinder of steel, and this numerical value is positioned within aforesaid numerical value 1 scope that comparatively is fit to satisfactorily.
Can adopt some modes to design shielding harness 170.It is to be noted: all embodiments all both can be used to do the catch tray 80 of permanent components, also can be used for disposable catch tray 80.
Accompanying drawing 4A is the amplification view of blade assembly 60 as shown in Figure 4, and it has represented a kind of optimum implementation that starts shielding harness 170 when driving blade assembly 60 automatically.
The feed roller 90 of shielding material is installed on the fixing supply shaft 102, and this is installed in the outside of feeder 80.This feed roller 90 can freely rotate on axle 102, so that provide shielding material 104 in mode described below.Feed roller 90 preferably can be taken off from axle 102 in a kind of known mode, so that can change feed roller 90.
A pair of gear 105 and 110 and central gears 115 are housed in the outside of catch tray 80.This central gear 115 is contained on the axle 116 that is fixed on the catch tray 80 in rotatable mode, and is meshed with gear 105 and 110 simultaneously.Central gear 115 can be freely with clockwise and counter rotation.
Gear 105 is installed on the unidirectional bearing 114, and the latter is installed on the axle 100 that is fixed on the framework 62.Gear 100 is installed on the take-up spool 120, and this two ends are contained on the both sides of catch tray 80, and passes the inside of catch tray 80 along the longitudinal direction.This take-up spool 120 is designed to the known mode that can replace of those of ordinary skill in this field, so that the operator can take off it when needed.As known, an end of take-up spool 120 is contained on the Engaging-and-disengaging bearing 112, and the latter is installed on the side of catch tray 80.
In operation, function driver 65 (perhaps using manual driven by knob 150 as mentioned above) makes blade assembly rotate in a clockwise direction around axle 100.In the driving process, folk prescription makes its lock shaft 100 on the installation direction of Engaging-and-disengaging bearing 114, and therefore when being driven into blade assembly 60 on the above-mentioned position, gear 105 is lockable, and can not rotate on axle 100.Like this, gear 105 becomes the bearing of " locked " when driving blade assembly 60, this rotates central gear 115 in a clockwise direction, driven gear 110 (with and take-up spool 120) counter rotation, the shielding material of having used 104 is involved in one section, draws in one section clean shielding material 104 from shielding material supply volume 90.Should suitably choose the number of teeth and the gearratio of gear 105,110 and 115,, the contact blade 68a that cleans blade 68 can be covered in cleaning operation process by clean shielding material so that from supplying the clean shielding material that volume 90 is left behind suitable length.Common required minimum is drawn in length and is about 1/4 inch.Like this, this device will be designed to just in time draw in the shielding material of Len req in cleaning operation, thereby prolong the life cycle of every volume shielding material 90 widely.
After cleaning operation was finished, driver 65 was released, and originally compressed spring 156 made blade assembly 60 do the counter-clockwise direction rotation around axle 100 now in the driving process.In order to prevent that used shielding material 104 is pulled back on the shielding material supply side reel 90, in blade assembly 60 d/d processes, make its lock shaft 120 on the installation direction of Engaging-and-disengaging bearing 112, to prevent take-up spool 120 (also preventing gear 110 simultaneously) rotation toward the clockwise direction.Gear 110 has become the gear of " locked " now, and central gear 115 is turned clockwise on axle 116.When blade assembly 60 is released, folk prescription is released to Engaging-and-disengaging bearing 114, and like this, gear 105 just can turn clockwise, and be meshed with gear 115, make the shielding material of having used 104 can be by being pulled back on the shielding material supply side reel 90 on the take-up spool 120.
Accompanying drawing 4b and 4c have represented the another kind of different modes that shielding harness is operated automatically.Wherein, tooth changes 105 and is installed in the end of pin 100 in the mode that can not rotate, and pin 100 then is contained on the framework 62.As seen, pin 100 will move in the deep-slotted chip breaker on the sidewall of catch tray 80 205.A guiding piece 200 is installed on the framework 62, and this guiding piece has a smooth contact-making surface 200a, and the mode that can slide with the outer surface of catch tray 80 contacts.As shown in the figure, guiding piece 200 entangles pin 100, moves along deep-slotted chip breaker 205a with the middle part that guarantees pin 100.
Shown in accompanying drawing 4a, gear 105 and central gear 115 are meshed.Wherein, central gear 115 is installed on the axle 116, and axle 116 then is fixed on the framework 62.Axle 116 can freely rotate in pair of bearings 116a, and this is installed in respectively on framework 62 and the catch tray 80 bearing.
